The research accomplished a literature review about acculturation on the earlier American Anthropologist journal. Acculturation research appeared on the North American Anthropology; later it came to Sociology and Psychology. The main models to approach acculturation followed the historical evolution of the North American cultures, and the earlier research barely considered the main dimensions of the acculturation concept. Assimilation and, in a lesser degree, fusion were the preferred models during colonial and imperial times, and the American Indigenous were the main researched cultural group. Acculturation was approached as one-way of cultural influences, and the Indigenous cultural change was the main concern. Yet, interaction and learning were not main concerns. The multicultural model appeared already in the earlier literature, however it was related to fusion.
